Building a Web Weather Station
One of my main concerns is lightning. Fortunately, our site is in a wooded area that is somewhat protected from direct lightning strikes. Still, I would feel even better if the remote weather sensors were electrically isolated from the display unit and my Linux machine. Some sort of optical isolation would probably work.
Also, I may have to develop an automated way to set the clock on the weather display unit.
Otherwise, the system seems to be working pretty well. With weatherd.pl running from the inittab, and with loop.pl in my startup rc files, the weather station monitoring continues after a reboot without manual intervention. Power loss or server failure will interrupt the service, but neither of those are common occurrences.
My weather station web page (see Figure 3) can be found at http://www.frii.net/~daylight/wscurrent.html. Please stop by and check it out. If you have the opportunity, come to Estes Park and see what a beautiful place it is.
